Sagen is a researcher at the Nansen Environmental and Remote Sensing Center. Her expertise is in applied mathematics specialized within ocean acoustic. Her research interests are focused on using new technologies for observing the Arctic environment, such as acoustic tomography, passive acoustics, floats and gliders. She was deputy-coordinator in the EU projects (AMOC (1998-2001) and ACOBAR (2008-2013)), and she led the follow up ACOBAR II project funded by RCN project.
DAMOCLES is an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic.
DAMOCLES aims at reducing the uncertainties in our understanding of climate change in the Arctic and their impacts. The Arctic over the last 2-3 decades has warmed more than other regions of the world, and the sea-ice cover has decreased significantly in the same period. A first-order scientific and societal question is whether the Arctic perennial sea-ice will disappear in a few decades (or even faster, as predicted by some state-of-art climate models).
